Cleopatra VII Philopator, known to history simply as Cleopatra, was the last active ruler of Ptolemaic Egypt, briefly survived as pharaoh by her son Caesarion. After her reign, Egypt became a province of the recently established Roman Empire.
Cleopatra was a member of the Ptolemaic dynasty, a family of Macedonian Greek origin that ruled Egypt after Alexander the Great’s death during the Hellenistic period. The Ptolemies spoke Greek throughout their dynasty, and refused to speak Egyptian, which is the reason that Greek as well as Egyptian languages were used on official court documents such as the Rosetta Stone. By contrast, Cleopatra did learn to speak Egyptian and represented herself as the reincarnation of the Egyptian goddess Isis.
Cleopatra originally ruled jointly with her father Ptolemy XII Auletes, and later with her brothers Ptolemy XIII and Ptolemy XIV, whom she married as per Egyptian custom, but eventually she became sole ruler. As queen, she consummated a liaison with Julius Caesar that solidified her grip on the throne. She later elevated Caesarion, her son with Caesar, to co-ruler in name.
The name Cleopatra is derived from the Greek name Κλεοπάτρα (Kleopatra) which meant “she who comes from glorious father” or “glory of the father” in the feminine form, derived from κλέος (kleos) “glory” combined with πατήρ (pater) “father” (the masculine form would be written either as Kleopatros, or Patroklos).
